T 0 all whom it may concern:

Be it known that I, DANIEL R. CooLEY, a subject of the King of GreatBritain, residin the Province of British Columbia and Dominion ofCanada, have invented new and useful Improvements in Window, Door, orPorch Screens, of which the following is a specification.

This invention relates to improvements in window, door or porch screens,the primary object being the provision of a screen, which will beautomatically opened to cover the space provided by opening a window,either from the bottom or top of the window frame.

Another object is the provision of a spring actuated roller screen,'inwhich the parts are housed either below or above the window and havingmeans extending to within convenient reach for releasing a springactuated screen roller holding dog, when it is desired to roll thescreen.

Another object is the provision of means, whereby screens of the abovecharacter may be used to inclose the porch, so that the screens may bequickly and easily rolled to anout-of-the-way position when desired, in-

stead of having to remove and store them away when not in use. 7

Other objects and advantages of the invention will appear as thefollowing description is read in connection with the accompanyingdrawings.

In the drawings:

Figure 1 is a View in elevation showing a window with the inventionapplied thereto, the portion of the wall or casing located directlybeneath the window being broken away or shown in section to more clearlyillustrate the invention.

Fig. 2 is an enlarged sectional View on the line 22 of Fig. 1.

Fig. 3 is a transverse sectional view through the window and screen.

Fig. 4 is a sectional view on the line 6-6 of Fig. 1.

Fig. 5 is a similar view on the line 5-5 of Fig. 1.

Fig. 6 is a view in elevation showing the manner of arranging the screenfor use as a porch screen.

Referring in detail to the drawings, wherein like characters ofreference denote corresponding parts, the frame of the window isindicated at 10, the upper sash at 11 and the lower sash at 12. Theinvention is illustrated as being applied to the lower windowSpecification of Letters Patent.

sash 12, but it is equally as well adapted for application to the uppersash, or both.

F or this purpose, there is provided a compartment or pocket 13, which,in the present instance is located beneath the window frame in the wallof the building. Mounted within this pocket or compartment is a shaft14, which is rotatable in bearings 15, suitably secured in position.Secured upon the shaft 14 1s a drum 16, which may be formed in anydesired manner, such as by securing disks near each end of the shaft toprovide guards or flanges for guiding the screen as it is being rolledupon the drum. The screen is indicated at 17 and is formed of wire meshand is provided with spaced transverse stiffen.- ing strips or braces18. One end of the screen is secured to and wound upon the drum and thescreen then extends upwardly through a slot-19 provided in the windowsill. The opposite end of the screen is then detachably secured to thelower end of the lower sash 12 as indicated at 19.

The drum is spring operated and for this purpose, there is provided atone end of the drum a housing 20, which incloses a coiled spring 21, oneend of which is secured to the to the housing 20 which is carried by thedrum. The opposite end of the drum is provided with a ratchet wheel 22,which is engaged by a spring actuated dog 23, preferably pivoted uponthe adjacent wall of the pocket or housing 13.

Secured to this dog is one end of an operating member herein shown inthe form of a flexible element or chain 24 which extends upwardlythrough the window sill and frame and passes over a roller or pulley 25,which is mounted upon a short shaft 26. The flexible element 24 thenpasses through an opening in the face of the window frame and isprovided with a handle or button '27, by means of which it may be pulledto release the dog 23 from engagement with the ratchet wheel 22.

In the use of the invention, when the sash is raised, the screen will becarried therewith and will be unrolled only a suiiicient length to coverthe space provided by the raising of the lower sash and will remain in ataut condition. hen it is desired to close the window, the handle 27 ofthe flexible element 24 is pulled to release the dog from the ratchetwheel, whereupon the window may be lowered. If desired the spring 21 maybe made sufiiciently strong to overcome the balance of the sash weight,so that upon release of the dog the sash will be lowered under theinfluence of the spring and by releasing the tension on the flexibleelement 24 the sash may be stopped at any desired point.

For the purpose of guiding the screen in its upward and downwardmovement, there is provided at each side of the window frame, apreferably metallic strip 28, which is provided with a longitudinalgroove 29 within which the screen operates. This strip 28 is substitutedfor the usual window strip provided for the purpose of guiding the lowersash, so that it performs the two-fold function of guiding both thescreen and the sash.

In. Fig. 6 of the drawings, the screen is shown as used for inclosing aporch and for this purpose, there is provided a frame 30, to which issecured bearings 31, for a shaft 32, the latter carrying a drum 33,which rotates in one direction under the influence of a spring inclosedin a housing 34. The drum is further provided with a ratchet Wheel 35and a spring actuated dog 36, which, like the dog 23 of the previouslydescribed form of the invention is controlled by a flexible element 37,which passes over a pulley 38 journaled'on the frame 30 and is providedwith an operating handle 39. The screen 40 is of similar constructiontothe screen 17 previously described, being provided with the braces orstiffening strips 41 and rolled upon the drum and having its side edgesguarded in grooved strips 42 secured along each side of the frame. The

a free edge may be provided with buttons 43,

to enable it to be securely fastened in closed properly fall within thescope of the ap-- pended claims.

Having claimed is 1. The combination with a window frame, of a springactuated drum mounted in bearings located beyond one end of the frame,

a screen or curtain wound upon said drum and extending thi ough a slot1n the adjacent end of the frame, means for removably securing the freeend of the screen or curtain to the window sash, a ratchet wheel securedto the drum, a spring actuated dog pivotally secured to the windowframe, and means secured to the dog and extending through the frame formoving the dog out of engagement with the ratchet wheel to regulate theposition of the window sash.

2. The combination with a window frame, of a spring actuated drummounted in bearings located beyond one end of the frame, a screen orcurtain wound upon said drum and extending through a slot in theadjacent end of the frame, means for removably securing the free end ofthe screen or curtain to the window sash, a ratchet mechanism forholding the drum aga nst movement in one direction, and means wherebythe drum may be released to regulate the position of the window sash.

In testimony whereof I affix my signature.
